I have been encouraging my nephews to consider this as well.

After nearly three decades of searching for ways to build superfast computers that operate on the principles of quantum mechanics, the reality of a fully-fledged quantum computer is moving closer, says professor Andrew Yao Chi-chih, dean of the Institute for Interdisciplinary Information Sciences, Tsinghua University, Beijing.

“Quantum computing is no longer viewed as a fad, or a scientist’s pie in the sky,’’ Yao told an audience of students, faculty, and invited guests during his presentation at a Hong Kong University of Science and Technology (HKUST) 25th Anniversary Distinguished Speakers Series event on January 28. Yao also took the opportunity to explain his rationale for quantum computing to be recognised as a Great Science. “Great Science involves the intersection of different scientific disciplines to create new knowledge that allows the exploration of the previously unimaginable,’’ stressed Yao, adding that Great Science also lifts the human spirit.

Yao believes computers built on the principles of quantum physics could revolutionise the information processes used for a range of applications, including precision weather forecasting and replacement aircraft fuselage wind tunnel testing. He also pointed out that increasingly powerful computers are needed to solve fresh challenges.

I cannot wait until Q-Dot technology is commercially available to industries. When we start releasing Q-Dots to the commercial sector we’re going to see some real magic happen and possibly even able to improve many things that are refined, or created today. https://lnkd.in/bF4xm73

Silicon wafers have long been the go-to for all things electronic. First appearing in the ‘50s, they quickly made it as THE connectors, basically singlehandedly kickstarting the silicon revolution. A team of researchers from the Cornell University have discovered something they consider to be the next big step in quantum electronics. They are quite certain of the answer to the question “Are Quantum Dots the Silicon Wafers of the Future?”.

1st; we all know in 30 years anything can change, wars can be fought & lost, natural disasters can occur, etc. However, posting for everyone’s amusement. 30 years ago which would be 1986; no one thought USSR would be broken up, 9/11 would happen creating the US Homeland Security, Lybia & Eygpt would overthrow their own leaders, that US Space missions would be outside the US Government, hacking at the levels we have today creating the CISO roles, of VR technology would exist, DNA and CRISPR would be discovered, etc.

So, who really knows what jobs will be fully automated v. not in 30 years or even created as a result of Quantum technology (Computing, Networking, Q-Dots for numerous thing that are not only technology, etc.). Just a fun article to share with everyone.

CSIRO says the Australian workplace of the future will be increasingly digitally-focused and automated, with titles such as online chaperone.

Very nice.

Quantum physicist Mario Krenn and his colleagues in the group of Anton Zeilinger from the Faculty of Physics at the University of Vienna and the Austrian Academy of Sciences have developed an algorithm which designs new useful quantum experiments. As the computer does not rely on human intuition, it finds novel unfamiliar solutions. The research has just been published in the journal Physical Review Letters. The idea was developed when the physicists wanted to create new quantum states in the laboratory, but were unable to conceive of methods to do so. “After many unsuccessful attempts to come up with an experimental implementation, we came to the conclusion that our intuition about these phenomena seems to be wrong. We realized that in the end we were just trying random arrangements of quantum building blocks. And that is what a computer can do as well — but thousands of times faster”, explains Mario Krenn, PhD student in Anton Zeilinger’s group and first author research.

After a few hours of calculation, their algorithm — which they call Melvin — found the recipe to the question they were unable to solve, and its structure surprised them. Zeilinger says: “Suppose I want build an experiment realizing a specific quantum state I am interested in. Then humans intuitively consider setups reflecting the symmetries of the state. Yet Melvin found out that the most simple realization can be asymmetric and therefore counterintuitive. A human would probably never come up with that solution.”

The physicists applied the idea to several other questions and got dozens of new and surprising answers. “The solutions are difficult to understand, but we were able to extract some new experimental tricks we have not thought of before. Some of these computer-designed experiments are being built at the moment in our laboratories”, says Krenn.

Australia’s improved alliance with China on defense, and Quantum Computing. Australia has been one of the early R&D groups working on Quantum Computing just like D-Wave, Stanford, UC Berkley, etc. So, this could help China drastically migrate much sooner to a Quantum infrastructure.

You think you’ve heard it before: Australia’s great security challenge this century is the dramatic shift in power to Asia epitomised by the rise of China.

But read of the latest Defence white paper if you want that abstract idea to sink in.

“Asia’s defence spending is now larger than Europe’s,” the paper states.

I am glad to see this article publish because it expresses well how technology and biological properties can be intertwined and advance collectively together. It will take this type of an approach to provide the foundation that is needed to enable the future visions that Kurzweil and others have shared around Singularity.

2 decades ago, Lucent experimented with the cells from fish to see how they could enable digital transmission through their experiments. They had some small successes; however, it never fully matured. Today, however, with Quantum we will finally see the advancements in technology, medicine, and science that many have only dreamed about or read from books or saw in movies.

Biological systems can explore every possible solution rapidly.

Interesting read; however, the author has limited his view to Quantum being only a computing solution when in fact it is much more. Quantum technology does offer faster processing power & better security; but, Quantum offers us Q-Dots which enables us to enrich medicines & other treatments, improves raw materials including fuels, even vegetation.

For the first time we have a science that cuts across all areas of technology, medical & biology, chemistry, manufacturing, etc. No other science has been able to achieve this like Quantum.

Also, the author in statements around being years off has some truth if we’re suggesting 7 yrs then I agree. However, more than 7 years I don’t agree especially with the results we are seeing in Quantum Networking.

Not sure of the author’s own inclusion on some of the Quantum Technology or Q-Dot experiements; however, I do suggest that he should look at Quantum with a broader lens because there is a larger story around Quantum especially in the longer term as well look to improve things like BMI, AI, longevity, resistent materials for space, etc/.

I recently read Seth Lloyd’s A Turing Test for Free Will — conveniently related to the subject of the blog’s last piece, and absolutely engrossing. It’s short, yet it makes a wonderful nuance in the debate over determinism, arguing that predictable functions can still have unpredictable outcomes, known as “free will functions.”

I had thought that the world only needed more funding, organized effort, and goodwill to solve its biggest threats concerning all of humanity, from molecular interactions in fatal diseases to accessible, accurate weather prediction for farmers. But therein lies the rub: to be able to tackle large-scale problems, we must be able to analyze all the data points associated to find meaningful recourses in our efforts. Call it Silicon Valley marketing, but data analysis is important, and fast ways of understanding that data could be the key to faster solution implementation.

The quantum world and our world of perception obey different natural laws. Leiden physicists search for the border between both worlds. Now they suggest an upper limit in a study reported in Physical Review Letters.

The laws of the quantum domain do not apply to our everyday lives. We are used to assigning an exact location and time to objects. But fundamental particles can only be described by probability distributions—imagine receiving a traffic ticket for speeding 30 to 250 km/h somewhere between Paris and Berlin, with a probability peak for 140 km/h in Frankfurt.

Boundary

Because the laws are completely different in both worlds, a clear boundary might exist between them. Size and mass could then be used to determine whether an object obeys quantum or macroscopic laws, but the edge of this boundary is elusive. Leiden physicist Tjerk Oosterkamp and his research group have now established established an upper limit for quantum phenomena, closing in on the answer.

Quantum mechanics is littered with different interpretations, but at the core of the entire school of thought is the question of whether there are multiple universes of not. At the core of this idea is the thought, explicated by quantum mechanics, that everything we observe is simply the collapse of all probable scenarios into one specific outcome. Reality, viewed from that perspective, has a very cluttered cutting room floor. But are the things removed from the reel scraps or alternative narratives? There’s the big question.

To answer that question, we need to dive a bit into the mechanisms of the thing. Quantum mechanics says that all particles in the universe can be represented by what are called “wave functions.” A single wave function basically illustrates all the information about a specific system (i.e. a particle), detailing everything from position to velocity. The wave function itself also outlines all the probable outcomes of that system as well.

In other words, the wave function says what a particle is, and — more importantly — what it might being doing any any given time. It represents all possible futures of that particle.
